BUCKLE.

SEECIFIUATION forming part of Letters Patent N 0. 717,524, dated January 6, 1903.

Application filed September 24, 1902. Serial No. 124,614. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES F.'ATwooD, a

I citizen of the United States, residing in Maling-supporters, if desired.

The nature of the invention is fully described below and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing the blank from which the clamping jaws are formed up and the wire loop separated, such being the two parts which constitute the clasp. Fig. 2 is an enlarged view of the clasp and a portion of the arm-band to which it is secured. Fig. 3 is a section taken on line 3, Fig. 2. Fig. 4 is a side elevation of the looped portion of the arm-band with my invention applied thereto. In this figure the parts are not taut and the band can he slipped freely through the wire loop of the clasp, and thus enlarged or contracted. Fig. 5 is a similar view of the band drawn taut or stretched, as it would be in position upon the arm.

Similar letters of reference indicate corresponding parts.

a represents the main portion of an elastic arm-band. One end of this portion is provided with a suitable clasp b, permanently secured in position and furnished with a wire loop The opposite end of the band a is passed through said wire loop and constitutes the looped portion a of the band. Any suitable looped contrivance may be applied in place of the one indicated at b 0, provided it is of such a nature that the part a of the band will slip freely through it.

B and 0 represent the two jaws, which are bent into the shape shown in Figs, 2, 3, 4, and 5 from the blank illustrated in Fig. 1. The jaw B is provided witha row of teeth E, so located that when the jaws are bent into the position indicated in Figs. 2, 3, 4, and 5 they project outward from the bend at substantially right angles to said jaw B, and the jaw O is provided near its edge with a row of inwardly bent teeth D, said teeth being formed by cutting triangular openings D from the jaw and bending up the teeth. The teeth E are formed by cutting triangular openings from the jaw B and bending the jaw B toward the jaw O, bending in addition the teeth E outward, if it is necessary, in order to bring them at right angles with the jaw.

The parts above described are substantially constructed and arranged as illustrated and set forth in Letters Patent of the United States No. 649,266 and granted to me on the 8th day of May, 1900, to which reference is made. In that invention a loosely-hinged wire loop is provided, which swings from the main portion of the clamp. It is found in practice that this swinging or hinged loop is sometimes apt to bind or catch or not move freely, with the effect that if the loop binds when it is out of line with the main portion of the clampthat is, at an angle therewiththe teeth will engage with or catch into the band when said band is slack or not stretched. My present invention or improvement is intended to obviate the difficulty, and it comprises the combination, with the main portion of the clamp, of a rigid loop K, which is held immovably by the clamp in a position substantially in line therewith, so that when the band is loose, as in Fig. 4, the loop cannot swing over and bind against it, so as to force said band into engagement with the teeth. The loop K is united rigidly with the main portion of the clamp by constructing it with the outwardly-projecting ends Kthat is to say, with the open portion non-parallel with the closed portion-said ends K extending diagonally between the two jaws B and U, as indicated by dotted lines in Fig. 2.

The main portion of the clamp is applied to the end of the part a of the band by placing it on the opposite sides thereof, the jaw B being placed on one side of the end portion of the loop a and the jaw 0 being placed on the other side, the clamp being held in posi tion by the teeth D, which engage the web, and the inwardly-extending ends K being tightly pressed between the web and the jaw B, so that in practice the shape of the ends K is indicated on the outer surface of the jaw B,

as shown in Figs. 2 and 3. Thus the main portion of the loop K extends out from the body of the clampin line therewith and rigid and relatively immovable. In this position 5 when the band is not taut its loop assumes the shape indicated in Fig. 4, and the teeth E lie parallel with and on the under side of the main portion a of the band. While in this po sition the band can be easily slipped through the wire loop K and the loop a made larger the clasp is drawn into a substantially parallel position with the band a, thus bringing the teeth E at right angles therewith. The loop K, which being rigid cannot swing out of line with the clamp, holds the teeth in engagenient in Fig. 5, but releases them from all pressure in Fig. 4, so that when the device is in the position shown in Fig. 4 the fabric can easily slip in the wire loop K.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is

1. A buckle consisting of the clamp portion comprising the two rigid jaws B, O, the jaw B being provided with outwardly-extending engaging teeth or prongs, and the jaw 0 being provided with inwardly-extending teeth or prongs for engaging the fabric; and the loop K rigidly secured to and extending from said clamp portion, substantially as described.

2. A buckle consisting of the clamp portion comprising the two rigid jaws B, G, the jaw B being provided with outwardly-extending engaging teeth or prongs, and the jaw 0 being provided with inwardly-extending teeth or prongs for engaging the fabric; and the loop K rigidly secured to and extending from said clamp portion in line therewith, substantially as set forth.

3. A buckle consisting of the clamp portion comprising the two rigid jaws B, O, the jaw B being provided with outwardly-extendingengaging teeth or prongs, and the jaw 0 being provided with inwardly-extending teeth or prongs for engaging the fabric; and the loop K rigidly secured to and extending from said clamp portion, said loop being provided with ends K extending inward between the jaws at angles with the bent or folded edge connecting said jaws, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
